The second sensor 12 detects the rotation angle of the swing member 6 from the rotation angle of the input shaft 12a. On the other hand, when the shift lever 9 is tilted in the left-right direction, the swing member 6 rotates about the select shaft 2, and the rotation is transmitted to the input shaft 10 a of the first sensor 10 via the engaging member 11, and One sensor 10 detects the rotation angle of the swing member 6 from the rotation angle of the input shaft 10a. Since the outer surface of the swing member 6 can slide with respect to the inner surface of the U-shaped engagement member 11, the swing member 6 is tilted around the axis of the shift shaft 1 with respect to the engagement member 11. Even in the state, the rotation of the swing member 6 around the axis of the select shaft 2 is transmitted to the engagement member 11, and the first sensor 10 can detect the rotation angle of the engagement member 11. A transmission (not shown) is controlled based on the detection value by the first sensor 10 and the detection value by the second sensor 12.

  According to the present invention, in order to assemble the rotational position detection type shift lever device, the lower end portion of the shift lever 9 is coupled to the swing member 6 and the gear 1c is provided at the position of the shift shaft 1 as shown in FIG. The lever member 19 shown in FIG. 5 is configured by supporting the swinging member 6 at both ends 2a and 2b of the select shaft 2 of the cross shaft 18 so as to be swingable.

Further, the shaft support structure of the select shaft 2 does not interfere with the input shaft 10a of the first sensor 10, and is brought into contact with a pair of side surfaces 6k parallel to each other across the second insertion hole 6c in the swing member 6. Since the engaging member 11 coupled to the input shaft 10a of the first sensor 10 sandwiches the swing member 6, it is possible to improve the assembling property and simplify the structure.

  Next, the first sensor 10 is attached to the sensor opening formed in the front wall 3e of the housing 3 from the outside of the housing 3, and the U-shaped engaging member coupled to the input shaft 10a of the first sensor 10 is attached. 11 engages with the swinging member 6 sandwiched from both sides. Since the first bushes 7 and 8 are inserted into the second insertion holes 6c to support the select shaft 2, the shaft support structure of the select shaft 2 does not interfere with the input shaft 10c of the first sensor 10 and swings. Since the engaging member 11 coupled to the input shaft 10c of the first sensor 10 is in contact with a pair of mutually parallel side surfaces 6k sandwiching the second insertion hole 6c in the member 6, the swinging member 6 is sandwiched. Can be improved and the structure can be simplified.

  When the cross shaft 18 having the swinging member 6 and the first sensor 10 and the second sensor 12 are inserted into the housing 3, and the other parts are considered as the child with the housing 3 as the parent, the children are independent. Therefore, the rotational position detection type shift lever device is easy to assemble. Further, since the cross shaft 18, the first sensor 10, and the second sensor 12 are attached to the housing 3 so as to be inserted, the structure can be simplified and no special tool is required. Furthermore, the number of parts can be reduced and the cost can be reduced. Further, since the cross shaft 18 is used, the offset between the shift shaft 1 and the select shaft 2 can be eliminated, and the rotational position detection type shift lever device can be miniaturized. If resin is used as the cross shaft 18, the weight can be reduced. It becomes possible.

The shift shaft is attached to the housing by forming a lower opening into which the cross shaft is inserted on the lower surface of the housing, and forming a third insertion hole for the shift shaft on the left and right side walls of the housing. The lower opening is formed with a second full length accommodating portion whose width in the left-right direction is slightly larger than the total length of the shift shaft,
The shift shaft is accommodated in the second full length accommodating portion by accommodating the cross shaft in the housing from the lower opening, and a cylindrical first is inserted into the third insertion hole from the outside of the left and right side walls of the housing. By inserting the two bushes, the end of the shift shaft is inserted into the second bush to support the shaft, and a fan-shaped gear is integrally formed on the shift shaft, while the input shaft of the second sensor Also, a fan-shaped gear is provided, and a cylindrical portion that opens to the left and right is integrally formed on the outside of the other front wall or rear wall of the housing, and the second sensor is inserted into the cylindrical portion, A rotational position detection type shift lever device characterized in that a meshing portion for meshing the pair of fan-shaped gears is disposed inside.
